TRACTOR.

Application' led pril. 7, 1922. Serial No. 550,320.

To all whom z't may concern.:

Be it known that I, GEORGE A. BRYAN, a citizen of the United States,residing at Peru, in the county of Miami and State of Indiana, haveinvented certain new and useful Improvements in Tractors,'of which thefollowingis a full, clear, and exact description.

My invention relates to tractors, and has especial reference to meansfor utilizing the quently t tractor as a stationary powerdevice. It liscustomary for this purpose to equip the tractor with a belt ulle whichis coupled to the machiner to e riven by a belt. Frelie pulley is on theend of a speclal transverse shaft provided for the purpose, which iseither operatively connected to the transmission gearing leading to thedifferential on the rear axle or has an independent drive connectionwith the engine. In

although some cases where the shaft is coupled to the transmissiongearing it is necessar to raise the rear wheels from the ground whenusing the tractor as a `.stationary power device, it has been proposedto provide means for alternately coupling the rst gear of thetransmission train with the pulley shaft drive and with the rest of thetransmission train.

In accordance with my invention, I simplify this construction byemploying a counter shaft adapted to receive and hold a ulley on oneprojecting end and properly ooated to drive the fan through gearing or land this counter shaft has permanendrive connection with thetransmission gearing in advance of disabling means provided to interruptthe connection -with the differential.

My invention also comprehends other features-,of construction anddetails and ar-.. rangement of partsas will hereinafter more" fullyappear. I shall now describe the illus trated embodiment of my inventionand shall thereafter point out my invention in claims. 4

Fig. 1 is a plan of a tractor embodying my invention;`

Fig. 2 is a side elevation of the same;

Fig. 3 is a front end elevation of the frame :fand pulley shaft andhousing support there- Fig. 4 is an enlarged sectional plan of the'parts at the pulley end of the shaft.

The illustrated tractor is steam propelled following generally thedesign of the vehicle illustrated in my co-pendingy application, SerialNo.` 535,167, filed Februa 9, 1922. Mounted on the front end of theghassis frame is a suitable steam generator 1 in front of which is acondenser' 2. In the rear of the steam generator is the steam engine 3and on the rear axlesuitably supported on the chassis frame is thetransmission gear case 4. The engine shaft 5 extends transversely of theframe and is supported in the rsplined a pinion 9 which isrshiftableinto and out of mesh with the spur gear Vwheel 10 on shaft 11, alsojournalled in bearings in the case 4 in rear of the shaft 8. A pinion 12on shaft 11 meshes with gear wheel 13 on the rear axle which isconnected to any suitable type' of diiferential. It is, therefore,apparent that the transmission train connectin the engine shaft with therear axle may e disabled by shifting the gear 9.

Secured to the left side of the transmission gear case4 is a ear box 14.The stub shaft 8 extends into t is gearbox 14 and has on its end a bevelgear 15 meshing with a bevel gear 15 on la longitudinally extending stubshaft 16. This stub shaft 16 is connected to and drives a universallyjointed, longitudinally extending shaft 17, the frontend of which iscoupled to a stub shaft 18 in a gear box 19 at the front end of thetractor.

The transverse fan drive and pulley shaft 20 which bears at its one endin the gear box els 19 is supported in the space between the' boiler landthe condenser 2 in the manner illustrated in Figures 2 and 3.Connecting the frontk ends of the side frame members' 21 and 22 is aframe front bracket 23 which is pinned at its central point to the frontaxle 24, and has at its ends two forwardly projecting arms 25 and 26 onwhich the condenser 2 is supported. Secured to the top of this. framefront bracket 23 is a pulley shaft housing support 27 on the one end ofwhich is supported the gear box 19 and on the opposite end of which' issupported the bearing 28 for the opposite vend of the pulley shaft.Midway between the gear box 19 and the bearing 28 is supported a fandrive gear box 29.

A bevel gear 3() on the stub shaft 18 meshes with a bevel gear 31 on theend of the pulley shaft in the gear box 19. Spiral gears in the'fandrive gear box 29 serve to drive the stub `shaft 32 on the front end ofwhich is secured a fan 33.

The end of the shaft 20 which projects beyond the bearing 28 is adaptedto receive and rotate the belt pulley 34. The end of the shaft has tworeductions in diameter, the first reduction forming a shoulder 35, andthe extreme end of the shaft is screw threaded. Surrounding the secondreduced portion of the shaft is a sleeve 36, the outer end of which isscrew threadednnd which has a circumferential flange 37. A nut 38 on thethreaded end of the shaft 20 clamps the sleeve 36 and a bushing 36a onthe first reduced portion tightly against the shoulder 35, thus lockingthe sleeve and shaft together against relative rotation, although otherwell-known means of non-rotatively ,securing the sleeve on the shaft maybe employed.

The pulley 34 has a central flat hub portion which fits over the sleeve36 and bears against the ange 37. Suitable means for locking the twotogether against relative rotation are employed, in this case studs 38abeing used for lthe purpose. The studs are carried by one of themembers, preferably the flange, and the other member, in this case thehub, is provided with properly spaced holes to receive the studs. A nut39 on the screw threaded end of the sleeve 36 locks the pulley in place.

By these means the pulley may easily be put on or removed. If desired, asuitable cap may cover the exposed end of the shaft when the pulley isremoved. It is obvious that various modifications may be made in theconstruction shown in the drawings and above particularly describedwithin the principle and scope of the invention.

I claim:

1. In a tractor having la rear axle, an engine the shaft of whichextends transversely of the tractor, an interruptable drive connectionbetween the engine shaft and rear axle, a power shaft extendinglongitudinally of the tractor and connected with the transverse engineshaft to be driven thereby, a
